How to Reinstall Windows 10 With an Installer CD or USB Drive?

As I have mentioned above, you can reinstall Windows 10 without a CD/USB drive or with it. If you already have a Windows 10 installer media (like a CD or a USB drive), then you can install a fresh copy of the OS on your system. Since the process is the same for both a CD and a USB drive, let’s explore it in detail.

Step 1: Create an Installer Media (CD/USB drive)

If you don’t have an installer CD or USB drive for Windows 10, then you can create one. For this, you can install and launch the Windows Media Creation tool and just connect the CD/USB drive to your computer. Once you have launched the tool, simply choose to create an installer media to proceed.

Creating a Windows Installer Disk

While setting up the installer media, you can choose to create a fresh copy of the firmware and retain some of your files and saved settings.

Step 2: Change the Booting Sequence on your system

Once the installer media is created, you can restart your computer and keep pressing the BIOS key (like F2, F9, F10, DEL, ESC, or any other key). As the BIOS settings are launched, go to the Boot tab and change the sequence (setting the priority to the attached CD or the USB drive).
